LinkedIn Staff Software Engineer Interview: Two Onsite Loops and a Final Reject

A candidate interviewed for a Staff Software Engineer role at LinkedIn's Sunnyvale office, going through two phone interviews and a six-round onsite loop that mixed leadership and craftsmanship questions with coding and system design problems. After the hiring committee decided the candidate was not a match for the Staff level, the candidate returned for a shorter, two-round onsite loop evaluated at the Senior Software Engineer level, which also ended without an offer.
